[Zope-dev] Re: [Interested?] New use for Zope+CMF+Archetypes -- startup time improvements
This is really interesting! A year ago I put Python + Zope on a USB key, just for fun. It would barely fit so I looked at zip techniques, and never could figure out how to get ZPTs etc. to load from a ZIP. How did you do that part? --Paul Dieter Maurer wrote: Dear Zope developers, we have used Zope+CMF+Archetypes in a new way -- not as a Web Application framework but as a framework for desktop applications that share a large part of their functionality with online applications (implemented with Zope+CMF+Archetypes). A major stumbling block has been Zope's incredibly high startup time. We observerd times in the order of a minute on computers with either slow CPU or slow IO. This may be acceptable for a Web server but is prohibitive for a desktop application -- especially as the predecessor application started within a few seconds. To overcome this obstacle, we tweaked Zope and fixed Python's import mechanism such that Zope now starts either out of a ZIP archive or as a frozen application. These measures had the following results. Startup times on a mid range computer (AMD Athon 1.4 GHz; 512 MB memory) with a standard IDE disk. Cold start Warm start (after computer startup)(most files in OS cache) File system13s5s ZIP archive 8s4s Frozen 5s3s In more details, we did: * implement a package for a new kind of urls pypackage: for package relative access to resources. The package monkey patches Python's open, os.listdir, os.stat to provide transparent access to pypackage: identified resources. It currently support package relative access for packages loaded from the file system, from a ZIP archive and from the executable itself (i.e. frozen packages). In the last case, the resources are in a separate ZIP archive. This package might be interesting for Python as a whole as it is not Zope specific. * implement a shared object importer to be used as a Python meta_path hook. This importer allows to load shared objects into the context of a parent package (such as e.g. ZODB.TimeStamp) although the shared object is not located inside the package's source (ZIP archive or executable). * fix about 70 occurrences in Zope code where package relative access was implemented by dirname(__file__) to consistenty use package_home. * modify about a dozen places in Zope+CMF to use pypackage: and cope with __path__ not being a list for frozen packages * fix a few products (Archetypes and friends, TextIndexNG2, PlacelessTranslationService, ...) to use package_home (rather than dirname(__file__)) and not to change the current working directory (which obviously would fail for destinationsbe in a ZIP archive or the executable). * implement lazy loading of ImageFiles to reduce the risk of recursive imports (and reduce startup time). * support lazy product initialization * support configuration from a pickle file (to avoid expensive parsing of the schema and configuration files). The pickle is used as a configuration cache. * fixed Python's import mechanism not to treat ZIP archives as a directory when the archive could not find a module. If you were *really* interested in these startup time improvements, I could provide patches which might be integrated in the Zope core for e.g. Zope 2.9. ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

[Zope-dev] inituser problem
Hi, I have a problem with the code in AccessControl.User.UserFolder._createInitialUser. It creates a user under what I feel are fairly bizarre circumstances. I feel it should simply use inituser if it's there and the user in it doesn't already exist in the root acl_users. Either that, or it should overwrite any user if the inituser file exists. The weird special case of one user being in the root acl_users seems extremely counterintuitive.

Re: [Zope] dollars-and-cents display fails

That's it right there! Before 5.0.3, they were unpacked, meaning
saved like a char. Now they are packed, fixed point numbers. This is
screwing up the python functions for fmt.
Well, I was trying to NOT redo all that code, but looks like I will
have to if I want to run the new mysql. I have tons of reports using
dtml and fmt. I think I'll stick with 5.0.0 for now until I have
time for that. (spent it all trying to figure out where my problem
was!)
Though, I might just switch to Firebird if I have to do some code
changing on my app anyway. It's a bit more mature than Mysql's new
stuff. (considering it's still in beta) Mysql is just so easy.

The Python decimal type is new in 2.4.
I don't think you've actually said whether or not you are actually
using a DECIMAL column.
I had forgotten that ZMySQLDA-2.0.9b3 always returns DECIMAL columns
as Python float. If you look in ZMySQLDA/db.py, you can see where it
does this in the DB class. You could try commenting this line out,
which will cause it to be returned as a string, and restarting Zope.
It's something to try, at least.

Re: [Zope] dollars-and-cents display fails
OK well, I fixed it. At least on My zope server.
The function for dollars-and-cents in DT_Var.py was like this:
def dollars_and_cents(v, name='(Unknown name)', md={}):
try: return $%.2f % v
except: return ''
I changed it to this:
def dollars_and_cents(v, name='(Unknown name)', md={}):
try: return $%.2f % float(v)
except: return ''
Problem solved. I just tested it in Mysql 5.0.0 and 5.0.4, and it
works great. I'll setup the rest of my app and test some more to make
sure I am not missing something. If there are any problems I'll post
more details.
Is this something that could be posted on the Zope Collector? It
should probably be tested on lots of other Db's I bet. But, one
question I have, should this be handled in the Mysql DA?

[Zope] Re: How do I logout using DTML
Dear Allen, please post your replies to the newsgroup as well. I tried both yours and the dtml-raise methods, but both of them didn't work. With yours I redirect myself out but I still logged in. With dtml-raise Unathorized, it popped out an password query box and kept ask me to input password for three time and went to an error page and I'm still logged in as well. Did I do anything wrong?? The dtml-raise should work. I don't know why isn't workning for you. Perhaps you stored the password in the browser or something like that, try deleting the stored passwords. About the popup window and the error message, as Jens post in the other message you started, this is the normal behaviour and can't be avoided. One way I can think about solving this behaviour is storing a hidden input field like go_to_logout, then check the request in the standard_error_message when an unauthorized exception occures and close the window with javascript if such variable is found. I know that zope can access the variables on the request after an error happens, but I'm not I'm not sure if this is going to work with an UnauthorisedException. For the second approach with the authorization cookies, you first have to make sure that you have installed CookieCrumbler and that you have created an instance of it. After doing this, the expiration cookies method should work. Once you install CookieCrumbler, you can modify the default login forms if you want.

[Zope] [ANN] TextIndexNG 3.0.0 final released
I am pleased to announce the final release of TextIndexNG V 3.0.0. TextIndexNG V 3 is a complete new implementation based on Zope 3 technologies and can be used both in Zope 2.8 or 2.7 (with Five) or in Zope 3. What's new? - multi-field indexing and query support - multi-lingual support - configurable converters (through ZCML) - new indexing API (allowing you to hook your custom content types with TextIndexNG through Zope 3 adapters). Requirements: - Zope 2.8 or Zope 2.7 (+ Five) or Zope 3 (Zope 3 has nothing like catalogs yet) TextIndexNG V3 will *not* run with bare Zope 2.7 installations without Five (and this will not be changed in the future). Download: http://sf.net/projects/textindexng For installation and documentation issues refer to doc/README.txt from the archive. It's basically the same procedure as with former versions except you *need* to recompile the extension modules. Windows binaries of the required extension modules are currently not available (any volunteers?). TextIndexNG V 3 is published under the GPL.

With this information, you can try to analyse the problem in an interactive Python interpreter. ... [Denis] To have either object or brain's path in output (tagencies list). The most interesting is that accessing via name I've got objects and paths [Dieter] this means that some paths could not be resolved (you get them as paths and cannot get objects). They probably form the old content still using request relative access. [Denis] but accessing via IP I've got ONLY object - no paths... [Dieter] In this case, all paths can be resolved into objects. You should select one or two failing paths and analyse them (this is done best in an interactive interpreter; under *nix, such an interpreter can be started with bin/zopectl debug). [Denis] Then I checked the paths I got for presence of objects on them. Objects are there, so I decided to use tagencies.append(portal.restrictedTraverse(path)) [Dieter] Try unrestrictedTraverse (will not work in untrusted code -- use the interactive interpreter). If unrestrictedTraverse can resolve the path, this means that the problem is a permission problem: the user is not allowed to access some object of path. The catalog tries two ways to resolve a path: the modern one uses physical path related traversal, the old one uses request relative Url traversal. Due to a bug introduced in a recent Zope version (and I think fixed again in Zope 2.7.6), the modern approach performs too strict access controls. This may mean that the request relative Url traversal is used as a fallback. The request relative Url traversal is known to have severe problems with virtual hosting (also it is not yet known why host specification via name or IP should make a difference). I (at your place) would debug brain.getObject() for one of the failing brains.

Re: [Zope] dollars-and-cents display fails
I guess my quick fix wont work. Well, it fixes the fmt for decimals,
but there's more to the issue. Statistical summaries, total, sum dont
work either.
In my dtml-in I might have this:
dtml-var total-decimalcolumn
or
dtml-var sum-decimalcolumn
These dont work with Mysql 5.0.4. So, what do we have to change in
the Mysql DA or maybe the Mysql-python to fix this?
If I find anything, I'll post more.

OK well, I fixed it. At least on My zope server.
The function for dollars-and-cents in DT_Var.py was like this:
def dollars_and_cents(v, name='(Unknown name)', md={}):
try: return $%.2f % v
except: return ''
I changed it to this:
def dollars_and_cents(v, name='(Unknown name)', md={}):
try: return $%.2f % float(v)
except: return ''
Problem solved. I just tested it in Mysql 5.0.0 and 5.0.4, and it
works great. I'll setup the rest of my app and test some more to make
sure I am not missing something. If there are any problems I'll post
more details.
Is this something that could be posted on the Zope Collector? It
should probably be tested on lots of other Db's I bet. But, one
question I have, should this be handled in the Mysql DA?

That's it right there! Before 5.0.3, they were unpacked, meaning
saved like a char. Now they are packed, fixed point numbers. This is
screwing up the python functions for fmt.
Well, I was trying to NOT redo all that code, but looks like I will
have to if I want to run the new mysql. I have tons of reports using
dtml and fmt. I think I'll stick with 5.0.0 for now until I have
time for that. (spent it all trying to figure out where my problem
was!)
Though, I might just switch to Firebird if I have to do some code
changing on my app anyway. It's a bit more mature than Mysql's new
stuff. (considering it's still in beta) Mysql is just so easy.

I compiled and installed Mysql 5.0.0 and the problem does not exist. I
guess means that it started in 5.0.1 or higher. I read through the
change logs and saw a couple of items related to float values on 5.0.3
and 5.0.4, but I dont have any idea if those are causing the issue.
So, I dont know where to go next. I can post this info on the mysql
lists, but I only see the problem in Zope. Python, or at least the
MysqlDA, retrieves the value just fine. I only get the problem if
using a fmt option on Zope.
Here's a recap:
-- I can use Zope 2.7.4 with Mysql 5.0.4 on Windows (using Egenix ODBC
DA) and there is no issue.
-- I can use Zope 2.7.3 with Mysql 5.0.0 on Linux (Zmysqlda 2.0.9b3,
Mysql-python1.2.0,Python 2.3.4) and there is no issue.
-- When using Zope 2.7.3 with same setup as before, but with Mysql
5.0.4, problem exists.
-- Zope 2.7.6 has same issue.
I tried doing a simple dtml:
dtml-call REQUEST.set('dec',10.23)
dtml-var decbr
dtml-var dec fmt=dollars-and-centsbr
This works just fine. But when pulling 'dec' from Mysql, dtml wont
render it if using fmt.
I dont have to use Mysql 5.x. It's just that I already have the app
running on it, and I'd like to start testing the stored procedures and
other useful features.
Sorry for the long post. I just want to give as much info as
possible. Thank you for any help!

I guess one of my main questions too is, would Zope be getting
